[0023] The working principle of this utility model is as follows: In use, the operator first installs the fabric combing machine 1 at the fabric outlet of the quilting machine, and the fabric cutting frame 2 is installed at the top right opening of the fabric combing machine 1. The fabric is guided into the fabric cutting frame 2. The adjustable auxiliary wheel 4 with fabric combing teeth plays a role in initially combing and smoothing the fabric. The adjustable auxiliary wheel 4 can adjust its height or pressure according to the thickness and material of the fabric. The teeth keep the height of the auxiliary wheel stable, ensuring that the fabric is properly combed and smoothed before entering the cutting area. Maintaining a flat, wrinkle-free surface, the infrared focuser 3 prepares for precise cutting as the fabric moves during operation. When the fabric reaches the vicinity of the cutting area, the infrared focuser 3 activates, emitting an infrared beam that illuminates the fabric. By detecting the reflected light from the fabric edge or the preset cutting position, the accurate position of the fabric is determined, providing precise positioning information for subsequent cutting and ensuring that the cutting blade 15 in the cutting box 5 can accurately cut to the predetermined position. When cutting is required, the drive motor 7 drives the sliding block to rotate the threaded shaft 8, and the sliding block guides the threaded shaft 9 to rotate. The movement of block 11 is guided to ensure that the sliding block 11 maintains linear motion during movement, preventing it from deviating or wobbling. Under the rotation of the sliding block drive threaded shaft 8, the sliding block 11 moves linearly along the sliding block guide threaded shaft 9. The sliding block limiting member 10 restricts the range of motion of the sliding block 11, ensuring that it moves within a predetermined stroke, thereby ensuring that the movement trajectory of the cutting blade 15 meets the cutting requirements. The electric telescopic rod 13 is connected to the sliding block 11 and reaches a predetermined position under the drive of the sliding block 11. The telescopic rod inside the electric telescopic rod 13... 14 can be extended and retracted according to specific cutting needs. When cutting fabrics of different thicknesses, the electric telescopic rod 13 can adjust the extension length of the telescopic rod 14 to keep the cutting blade 15 at a suitable distance from the fabric surface for cutting action, ensuring the cutting effect. After cutting, the adjusting motor 22 uses a combination of multiple components, including the adjusting drive spindle 23, transmission gear 24, adjusting drive threaded shaft 25, and push rod drive threaded bearing 26, to drive the push rod 17 to extend. The operator can then remove the fabric shaft 20 and replace it with a new one.
